Field strength to eirp
Effective radiated power and effective isotropic radiated power both measure the power density a radio transmitter and antenna (or other source of electromagnetic waves) radiates in a specific direction: in the direction of maximum signal strength (the "main lobe") of its radiation pattern. This apparent power is dependent on two factors: the total power output and the radiation pattern of the antenna – how much of that power is radiated in the desired direction. The latter factor is quantif… WebJul 7, 2024 · Electric field strength or electric field intensity is the synonym of electric field.

RSSI: signifies the signal strength at a location in the coverage area of a wireless network. It is the value of the EIRP minus the transmission path loss and signal attenuation caused by obstacles. Weak signal strength means that the RSSI is lower that the edge field strength.
WebFor field strength in dBu: (60-6) E(dbuV/m) = 106.92 + ERP(dBk) - 20LogD(km) For received power: (60-10) P(dBm) = E(dbuV/m) + Gr(dBi) - 20LogF(MHz) - 77.2 Substituting the received field: P(dBm) = 106.92 + ERP(dBk) - 20LogD(km)+ Gr(dBi) - 20LogF(MHz) - 77.2 For a 0dBi receiver antenna (Gr): P(dBm) = 106.92 + ERP(dBk) - 20LogD(km)
